Method Detail

getPerpendicularOffset

public Expression getPerpendicularOffset()

Description copied from interface: PolygonSymbolizer

PerpendicularOffset works as defined for LineSymbolizer, allowing to draw polygons smaller or larger than their actual geometry. The distance is in uoms and is positive to the outside of the polygon. Negative numbers mean drawing the polygon smaller. The default offset is 0.

Specified by:

getPerpendicularOffset in interface PolygonSymbolizer

Returns:

Expression

setPerpendicularOffset

public void setPerpendicularOffset(Expression offset)

Description copied from interface: PolygonSymbolizer

PerpendicularOffset works as defined for LineSymbolizer, allowing to draw polygons smaller or larger than their actual geometry.

Specified by:

setPerpendicularOffset in interface PolygonSymbolizer

Parameters:

offset - Offset from the edge polygon positive outside; negative to the inside with a default of 0.

getDisplacement

public Displacement getDisplacement()

Description copied from interface: PolygonSymbolizer

The Displacement gives the X and Y displacements from the original geometry. This element may be used to avoid over-plotting of multiple PolygonSymbolizers for one geometry or supplying "shadows" of polygon gemeotries. The displacements are in units of pixels above and to the right of the point. The default displacement is X=0, Y=0.

Specified by:

getDisplacement in interface PolygonSymbolizer

Returns:

Displacement

setDisplacement

public void setDisplacement(Displacement displacement)

Description copied from interface: PolygonSymbolizer

Provide x / y offset in pixels used to crate shadows.

Specified by:

setDisplacement in interface PolygonSymbolizer

getFill

public Fill getFill()

Provides the graphical-symbolization parameter to use to fill the area of the geometry.

Specified by:

getFill in interface PolygonSymbolizer

Returns:

The Fill style to use when rendering the area.

setFill

public void setFill(Fill fill)

Sets the graphical-symbolization parameter to use to fill the area of the geometry.

Specified by:

setFill in interface PolygonSymbolizer

Parameters:

fill - The Fill style to use when rendering the area.

getStroke

public StrokeImpl getStroke()

Provides the graphical-symbolization parameter to use for the outline of the Polygon.

Specified by:

getStroke in interface PolygonSymbolizer

Returns:

The Stroke style to use when rendering lines.

setStroke

public void setStroke(Stroke stroke)

Sets the graphical-symbolization parameter to use for the outline of the Polygon.

Specified by:

setStroke in interface PolygonSymbolizer

Parameters:

stroke - The Stroke style to use when rendering lines.

accept

public Object accept(TraversingStyleVisitor visitor,
                     Object data)

Accepts a StyleVisitor to perform some operation on this LineSymbolizer.

Specified by:

accept in interface PolygonSymbolizer

Specified by:

accept in interface Symbolizer

Parameters:

visitor - The visitor to accept.

Returns:

value produced

accept

public void accept(StyleVisitor visitor)

Specified by:

accept in interface Symbolizer

clone

public Object clone()

Creates a deep copy clone. TODO: Need to complete the deep copy, currently only shallow copy.

Specified by:

clone in interface Cloneable

Overrides:

clone in class Object

Returns:

The deep copy clone.

hashCode

public int hashCode()

Overrides:

hashCode in class AbstractSymbolizer

equals

public boolean equals(Object obj)

Overrides:
